You've received a startup equity offer. Maybe it's your first — a grant of stock options at a company you're excited about — or maybe you've seen a few and you know enough to be dangerous. Either way, the equity component of your compensation is likely the part with the most upside and the most uncertainty.
Having advised both startups and the people who join them for over 25 years, I've seen equity negotiations go well and go badly. The difference almost always comes down to whether the employee understood what they were negotiating and asked the right questions at the right time.
This guide is for employees — engineers, executives, early hires — who want to understand their equity offer, evaluate whether it's fair, and negotiate effectively.
01. Understand What You're Being Offered
Before you negotiate, you need to understand exactly what's on the table. Most startup equity offers include these components:
Number of shares or options. This number is meaningless without context. 100,000 shares sounds like a lot — but if the company has 100 million shares outstanding, you own 0.1%. The number of shares only matters relative to the total.
Percentage ownership. This is what actually matters. Ask: "What percentage of the company's fully diluted shares does this grant represent?" Fully diluted means all shares outstanding, plus all shares reserved in the option pool, plus any outstanding convertible instruments (SAFEs, convertible notes). Some companies will only tell you outstanding shares — which makes your percentage look larger than it actually is.
Exercise price (for options). This is the price you'll pay per share when you exercise. It should be set at the current 409A fair market value. If it's not, the options may have adverse tax consequences under Section 409A.
Vesting schedule. The standard is four years with a one-year cliff: you vest nothing for the first year, then 25% on your one-year anniversary, and the remainder monthly over the next three years. Variations exist — three-year vesting, six-month cliffs, back-loaded schedules — and they matter.
Option type: ISO or NSO. Incentive Stock Options have better tax treatment than Nonqualified Stock Options. You want ISOs if you're eligible (you must be an employee of a C-Corp). Ask which type you're being granted.
Practice Note: If the company won't tell you the total number of fully diluted shares, that's a yellow flag. You cannot evaluate your equity without this information. Any company that's serious about hiring you should be willing to share it — at minimum, the approximate number.
02. How to Evaluate Whether Your Offer Is Fair
Look at percentage, not share count. A common anchoring tactic (sometimes unintentional) is to emphasize the number of shares: "We're offering you 50,000 options!" Without knowing the total shares outstanding, this number tells you nothing.
Benchmark by role and stage. Equity grants vary significantly by company stage and role. As a rough guide for non-founder employees:
- First engineering hire (pre-seed): 1%–2%
- Early engineer (seed): 0.25%–1%
- Senior engineer (Series A): 0.1%–0.5%
- VP/Director (seed): 0.5%–1.5%
- VP/Director (Series A): 0.25%–0.75%
- C-suite (seed): 1%–3%
- C-suite (Series A): 0.5%–1.5%
These ranges vary by market, geography, company traction, and individual negotiating leverage. Use them as a starting point, not a rule.
Calculate the potential value. Take your percentage ownership, multiply it by a range of potential exit valuations, and subtract your exercise cost. This gives you a rough (very rough) sense of what your equity could be worth.
Example: You're offered 0.5% of a seed-stage company. Your exercise price is $0.25/share for 50,000 shares ($12,500 total). If the company is eventually acquired for $100 million, your 0.5% is worth $500,000 before dilution and taxes. At a $500 million exit, it's worth $2.5 million. At zero, it's worth zero.
Factor in dilution. Your percentage will shrink with every subsequent funding round. A typical startup raises three to four rounds of financing, each of which dilutes existing shareholders by 15%–25%. Your 0.5% at the seed stage could be 0.2%–0.3% by the time of an exit. This is normal — the pie gets bigger even as your slice gets proportionally smaller.
03. The Questions You Must Ask
These are the questions that separate informed candidates from everyone else. Ask all of them before accepting an offer:
1. What is the total number of fully diluted shares?
This lets you calculate your actual ownership percentage.
2. What is the current 409A valuation (fair market value per share)?
This tells you the current implied value of the company and confirms your exercise price is reasonable.
3. What is the most recent preferred share price?
If the company has raised venture capital, the preferred share price from the last round gives you a market-based estimate of the company's value. The gap between the preferred price and the 409A valuation (common stock price) is your built-in discount.
4. What is the vesting schedule, and is there a cliff?
Confirm the standard four-year / one-year cliff, or understand how the company's schedule differs.
5. Are these ISOs or NSOs?
ISOs are meaningfully better from a tax perspective. If you're being offered NSOs, ask why (there may be a valid reason, such as the company being an LLC, or you being a consultant).
6. What happens to my options if I leave?
Standard option agreements give you 90 days to exercise after departure. Some companies offer extended exercise windows (one to ten years). This matters enormously — if you leave and can't afford to exercise within 90 days, your options expire worthless.
7. Is there an early exercise provision?
Early exercise lets you buy shares before they vest and file an 83(b) election, potentially converting future gains from ordinary income to long-term capital gains. This is valuable at early-stage companies with low exercise prices.
8. Is there double-trigger acceleration?
If the company is acquired and you're terminated, does your unvested equity accelerate? This protection is increasingly common and worth negotiating.
9. What's the company's current burn rate and runway?
This tells you how long the company can operate before it needs more funding. If runway is six months, your equity may be worth nothing if the next round doesn't happen.
10. Has the company ever done a secondary sale or tender offer?
This tells you whether there's any path to liquidity before an IPO or acquisition.

04. What You Can Actually Negotiate
Many candidates assume equity grants are take-it-or-leave-it. They're not — particularly for senior hires, hard-to-fill roles, or candidates with competing offers.
More shares / higher percentage. The most direct negotiation. If the offer is 0.25% and you believe the role warrants 0.5%, make the case. Back it up with market data, your experience, or competitive offers.
Shorter vesting or modified cliff. You can negotiate for a shorter vesting period (three years instead of four), a shorter cliff (six months instead of twelve), or no cliff at all. A shorter cliff is often easier to get than more shares.
Acceleration on change of control. As discussed in my guide on double-trigger acceleration, this protects you if the company is acquired and your role is eliminated. Many standard option plans include this, but if yours doesn't, negotiate it into your offer letter.
Extended post-departure exercise window. The standard 90-day exercise window is punitive — it forces you to exercise (and pay for) your vested options within three months of leaving, or lose them. Negotiating a longer window (one year, or even ten years) gives you flexibility and eliminates the "golden handcuffs" problem. Some companies now offer this as a standard term.
Early exercise. If the company doesn't currently allow early exercise, you may not be able to change the plan — but it's worth asking. For very early-stage companies, early exercise combined with an 83(b) election is one of the most valuable equity features available.
Refresher grants. Ask about the company's policy on additional equity grants after you've been there a year or two. Some companies grant annual refreshers; others don't. Understanding the policy upfront helps you evaluate the total equity picture.
Key Principle: The most effective negotiation tactic is having alternatives. A competing offer — even from a different type of company — gives you leverage. If you don't have one, your leverage comes from being genuinely hard to replace in the role. Know your value.
05. Red Flags in Equity Offers
Watch for these warning signs:
The company won't share fully diluted share count. If they refuse to tell you how many total shares are outstanding, you can't evaluate the offer. Walk away or insist.
The exercise price seems too low or too high. If the exercise price hasn't been set by a qualified 409A valuation, the options may have tax problems under Section 409A. Ask when the last 409A valuation was done and by whom.
There's no standard vesting schedule. Unusual vesting terms — back-loaded vesting, no cliff, or very long vesting periods (five or six years) — may indicate that the company is trying to lock you in on unfavorable terms.
90-day exercise window with high exercise costs. If you have ISOs with a high exercise price and only 90 days to exercise after leaving, you may face a situation where you can't afford to exercise — meaning you'll forfeit equity you've already earned. Ask for an extended window.
Excessive option pool. If the company has reserved a very large option pool (30%+ of fully diluted shares), your percentage may be diluted significantly by future grants to other employees. Ask how much of the pool has been allocated.
No talk of 83(b) elections. If you're receiving restricted stock or early-exercisable options and no one mentions the 83(b) election, that's concerning. The company should be proactively advising you about this critical tax election.
Verbal promises about equity. If the founder says "we'll give you more equity later" or "we'll adjust your grant after the next round," get it in writing. Verbal promises about equity are unenforceable and frequently forgotten.
06. Taxes: What You Need to Know Before You Sign
Your equity offer's after-tax value depends on decisions you make now — not at exit.
ISOs vs. NSOs. ISOs defer tax until you sell the shares (assuming you meet the holding period requirements). NSOs trigger ordinary income tax at exercise. For most employees, ISOs are significantly better — but the AMT implications of ISO exercise need to be understood.
The 83(b) election. If you receive restricted stock or early-exercise your options, you have exactly 30 days to file an 83(b) election with the IRS. Missing this deadline is irreversible and can cost you tens or hundreds of thousands of dollars in unnecessary taxes.
The $100K ISO rule. ISOs that first become exercisable in a calendar year are only treated as ISOs up to $100,000 in value (based on the fair market value at grant). Any excess is automatically treated as NSOs. This matters if you have a large grant or if acceleration causes a large number of ISOs to vest at once.
QSBS eligibility. If the company is a C-Corp and meets the Section 1202 requirements, gains on your stock may be eligible for the QSBS exclusion — potentially up to $10 million in tax-free gains. The five-year holding period starts when you acquire the stock (at exercise for options, at grant for restricted stock with an 83(b) election). This is another reason to exercise early when possible.

07. Negotiation Mistakes to Avoid
Focusing only on salary. Many candidates spend all their negotiation capital on a $10,000 salary increase and accept the equity offer as-is. In a successful outcome, the equity is worth multiples of the salary difference. Allocate your negotiation energy accordingly.
Comparing share counts across companies. "Company A offered me 100,000 shares and Company B offered 50,000" is meaningless without knowing each company's total share count, exercise price, and valuation. Compare percentages and estimated values, not share counts.
Not understanding the exercise cost. Your options aren't free — you'll need to pay the exercise price to acquire the shares. At early-stage companies this might be $5,000. At later stages, it could be $50,000 or more. Make sure you can afford to exercise, and understand when you'd want to.
Ignoring the tax consequences. The difference between ISOs and NSOs, the availability of early exercise, and the 83(b) election can change your after-tax outcome by hundreds of thousands of dollars. Don't treat these as minor details.
Not getting the offer in writing. Your equity grant should be documented in a formal stock option agreement or restricted stock purchase agreement, not just an offer letter. The offer letter should reference the specific equity terms, and you should receive the actual agreement before or shortly after starting.
08. FAQ
How much equity should I ask for?
It depends on your role, the company's stage, and your leverage. Use the benchmarks in Section 02 as a starting point, and adjust based on the company's traction, your experience, and competing offers. The key is to negotiate in terms of percentage, not share count.
Can I negotiate equity after I've already accepted the offer?
It's much harder. The best time to negotiate is before you accept. Once you've started, your leverage drops significantly — though you may be able to negotiate during a subsequent funding round or annual review cycle.
What if the company says equity grants are standardized and non-negotiable?
This is common at later-stage startups with established compensation bands. If the equity is truly non-negotiable, focus on other terms: exercise window, acceleration, vesting schedule, or signing bonus. At earlier-stage companies, equity is almost always negotiable.
Should I exercise my options early?
If the exercise price is low (under $10,000–$20,000 total), early exercise with an 83(b) election can be very advantageous — it starts the QSBS clock and converts future gains to long-term capital gains. If the exercise price is high, the risk of paying a large amount for shares in a company that may not succeed needs to be weighed carefully.
How do I know if my equity will ever be worth anything?
You don't — and anyone who tells you otherwise is guessing. Startup equity is a high-risk, high-reward bet. Evaluate it as part of your total compensation, don't depend on it for near-term financial needs, and make sure your base salary is enough to live on comfortably.
What if I'm joining as a contractor, not an employee?
Contractors typically receive NSOs (not ISOs) or restricted stock. The tax treatment and negotiation dynamics are similar, but contractors should pay particular attention to how their equity is classified for tax purposes and whether they're eligible for QSBS treatment.
The Bottom Line
Startup equity can be life-changing compensation — but only if you understand what you're getting, negotiate effectively, and make the right tax elections at the right time.
The three most important things to remember:
- Evaluate your equity as a percentage, not a share count. Always ask for the fully diluted share count.
- Understand the tax consequences before you sign. ISO vs. NSO, 83(b) elections, and exercise timing can save or cost you hundreds of thousands of dollars.
- Negotiate the terms, not just the amount. Exercise window, acceleration, and vesting schedule can matter as much as the number of shares.
